Abstract

A device for transporting specimens carried on microscope slides through a plurality of liquid containing jars for staining or otherwise treating the specimens. It includes a rail, a conveyor chain, a conveyor motor, an elliptically shaped rod, a rod motor, a plurality of open top jars, a plurality of carriers, and a plurality of slide holders. The jars are positioned along a horizontal path. Each slide holder is pivotally connected to a carrier so that its slide holding portion will extend into a jar or be lifted above the jar when the rod is rotated counter-clockwise 90.degree. from its horizontal position to its vertical position. Subsequent continuous counterclockwise rotation of the rod will alternately permit slides to be lowered by gravity and raised by the force provided by the rod. The carriers and slide holders with slides attached are supported by the rail, moved horizontally by the conveyor chain parallel to the path, and agitated up and down by the rod. The rod has the double purpose of lifting slides over any obstructing jar wall and of agitating slides for faster and more uniform infiltration of the specimens.
